Background/aim: β-Catenin is one of the key players in colonic carcinogenesis. Being part of the E-cadherin complex, it regulates cell-cell adhesion and the migratory ability of cells. However, the role of nuclear β-catenin in the cell migration process is poorly understood. Gelsolin is one of the most abundant actin-binding proteins, and is implicated in tumour cell motility and invasiveness. The aim of the present study was to evaluate the potential association between expression of β-catenin and gelsolin, and their influence on the migration ability of colon adenocarcinoma LS180 cells.
Materials And Methods: The colonic adenocarcinoma cell line LS180, its more motile sublines (EB3, 3LNLN, 5W) and β-catenin-knockdown LS180 cells were used to investigate the expression levels and subcellular localization of β-catenin and gelsolin.
Results: Increased motility of colonic cancer cells was accompanied by a reduction of β-catenin and up-regulation of gelsolin.
Conclusion: β-Catenin seems to be involved in the regulation of gelsolin expression, which in turn affects the migratory ability of colonic cancer cells. Our results could have important implications for the design of new anticancer therapies.

Atherosclerosis risk is elevated in diabetic patients, but the underlying mechanism such as the involvement of macrophages remains unclear. Here, we investigated the underlying mechanism related to the pro-inflammatory activation of macrophages in the development of diabetic atherosclerosis. Bioinformatics tools were used to analyze the macrophage-related transcriptome differences in patients with atherosclerosis and diabetic mice.

Background: Clear cell renal cell carcinoma (ccRCC) has a high incidence rate and poor prognosis, and currently lacks effective therapies. Recently, peptide-based drugs have shown promise in cancer treatment. In this research, a new endogenous peptide called CBDP1 was discovered in ccRCC and its potential anti-cancer properties were examined.

Tongue squamous cell carcinoma (TSCC) is a common malignant oral cancer characterized by substantial invasion, a high rate of lymph node and distant metastasis, and a high recurrence rate. This study aims to provide new ideas for the diagnosis and treatment of TSCC patients by exploring the related mechanisms that affect the migration and invasion of TSCC and inhibit the migration and spread of cancer cells. The results indicated the rate of high expression of IL-17 in cancer tissues was greater than that in tongue tissues, and the expression of IL-17 was related to the TNM stage.

Background: Pancreatic ductal adenocarcinoma (PDAC) exhibits a high frequency of neural invasion (NI). Schwann cells (SCs) have been shown to be reprogrammed to facilitate cancer cell migration and invasion into nerves. Since extracellular vesicles (EVs) affect the tumour microenvironment and promote metastasis, the present study analysed the involvement of EVs from pancreatic cancer cells and their microenvironment in altering SC phenotype as part of the early events in the process of NI.

An ideal chemotherapeutic agent damages DNA, specifically in cancer cells, without harming normal cells. Recently, we used Box A of HMGB1 plasmid as molecular scissors to produce DNA gaps in normal cells. The DNA gap relieves DNA tension and increases DNA strength, preventing DNA double-strand breaks (DSBs).
